Tideway wanted to celebrate the completion of tunneling of its 25km Super Sewer. It was a feet of engineering and the start of the recovery of the Thames river ecosystem, but there was only a small window of time to physically enter it. The sound acoustics within the tunnels are unique, so with our small window of opportunity, we realised we could create a Sonic Time Capsule of the tunnels, in the form of a specially produced song.
